The donation includes $8 million to endow one faculty chair each in the areas of pulmonology, nephrology, neurology and general pediatrics.

The Steads chair a fundraising campaign aimed at attracting $500 million in private donations. The university says their gift pushes the campaign’s total to $505 million. The Steads’ previous $10 million gift in 2011 also was to the children’s hospital.

The pediatrics department will be named the University of Iowa Stead Family Department of Pediatrics.

The Steads donated $25 million to the university’s Tippie College of Business in 2003.
